Underwater sound response test equipment

Abstract

To enable a test of an influence of sound on an aquatic organism at a desired sound pressure level.SOLUTION: An underwater sound reaction test device includes: a first water tank storing water; a second water tank that is arranged inside the first water tank and breeds an aquatic organism; and a speaker that is arranged above the first water tank and outputs sound toward the second water tank. An acoustic impedance of the second water tank is determined so as to match an acoustic impedance of the water stored in the first water tank.SELECTED DRAWING: Figure 1
